Pakistan has dismissed as "speculative" the reports that the United States has information about the location of its nuclear assets.
"There is no truth... Essentially such claims are to add spice to contentious speculations and reports that go around," 'The News' reported in Islamabad on Tuesday, quoting Foreign Office spokeswoman Tasnim Aslam as saying.
The statement came days after media reports claimed "the United States has full knowledge about the location of Pakistan's nuclear weapons and is worried who would control the weapons in the hours after any change in government in case Musharraf was killed or overthrown".
"Musharraf controls the loyalty of the commanders and senior officials in charge of the nuclear programme, but those loyalties could shift at any point," the media had reported, quoting American intelligence officials as saying.
The US's not certain who might start controlling nuclear launch codes and weapons if that shift in power were to happen, the unnamed officials reportedly said, claiming America's assessing the current situation in Pakistan.
"There's also a growing understanding that Musharraf's control over the military remains limited to certain top commanders and units, raising worries about whether he can maintain control over the long term," according to them.
The US officials had also said that one of the key problems for the American military "is what restriction on US-Pakistani military cooperation could be imposed if Musharraf were to impose heavy security restrictions in the Islamic nation".
